How Does Soda Work With Cake Mix?

The soda contains carbon dioxide bubbles. These little bubbles act as a leavening agent and also replace the wet ingredients you’d usually add to a boxed cake mix (eggs, oil, etc.) The result is a light and fluffy cake that’s full of extra flavor!

Cake Ingredients:

• 1 can orange soda (such as Sunkist)
• 1 box white cake mix (15 ounce box)

Creamsicle Frosting Ingredients:

• 1 cup orange soda
• 1/2 cup butter
• 4 cups powdered sugar
• 1-2 TB milk

Optional Garnish Ideas

• Orange sprinkles
• Orange slices

Helpful Kitchen Tools

• 9×11″ baking dish
• Small saucepan
• Mixing bowls

Instructions

To Prep: Preheat oven to 350°F and grease a 9×11″ baking dish.

Cake Directions:

1. In a large bowl, beat together the cake mix and orange soda for 2 minutes.
2. Pour into prepared pan and bake for 25-30 minutes, or until a toothpick inserted in the middle of the cake comes out clean.
3. Allow cake to cool completely before frosting with your favorite frosting, or our homemade creamsicle icing (recipe below).

Icing Directions:

1. Pour 2 cup orange soda into a small saucepan and bring to a boil.
2. Reduce heat and simmer until the soda reduces to about 1/4th the original volume (or until about 2 ounces remain). Allow to cool completely.
3. In a large bowl, beat together the butter and powdered icing sugar for 2 minutes, then add the reduced Sunkist soda. Beat to incorporate, then add the milk as needed to achieve a spreadable texture. Adjust the color with orange food dye, if desired.
4. Use an offset spatula to frost the cooled cake.
5. Garnish with sprinkles and orange slices (optional).

Prep Tips

• To achieve the fun texture shown in the pictures, use short strokes to spread the frosting, then go back over the frosted cake and rough it up a bit.
• We used orange sugar sprinkles on our cake – they give the cake a little pop of crunch that really reminds me of soda! You’re welcome to use your own favorite toppings.
• You don’t have to use the homemade icing recipe above. A great time saver is using whipped topping, such as Cool Whip, for the frosting. You could also use canned frosting.
